Abstract Nanoparticles of mesoporous MIL‐100(Al, Cr or Fe) metal–organic frameworks were synthesized by a microwave‐assisted solvothermal route with green solvents. The optimization yield, crystallinity, and particle size was achieved through the control synthetic parameters such as temperature, heating rate, dwelling time. strongly depends on metallic cation metal linker precursors; nanoparticles smaller than 100 nm obtained for iron chromium based MIL‐100. Finally, stable colloidal...
The high porosity and versatile composition of the benchmarked mesoporous metal (Fe, Al, Cr) trimesate metal-organic frameworks (MIL-100(Fe, Cr)) make them very promising solids in different strategic industrial societal domains (separation, catalysis, biomedicine, etc.). In particular, MIL-100(Fe) nanoparticles (NPs) have been recently revealed to be one most innovative next generation tools enabling multidrug delivery overcome cancer resistance. Here, we analyzed vitro toxicity potential...
Benchmarked micro or nanosized HKUST-1, ZIF-8 and Fe3(BTC)2 as well template-assisted metal–organic frameworks (MOFs) of various morphologies were synthesized via a green scalable aerosol route. Their high space time yields make this continuous method very promising for the industrial production shaping MOFs.
A series of nanometric isoreticular and/or functionalized analogues the mesoporous environmentally-friendly iron(III) polycarboxylates MIL-100/101 have been successfully synthesized. Their exceptional pore size, up to 68 Å, together with their relatively good stability in solvents, makes them promising candidates for heterogeneous catalysis or inclusion large molecules, among others.
Poly(ionic liquid)s with well-defined chemical structure were prepared and applied as precursors for nitrogen-doped carbon fibers membranesvia the electrospinning technique. The nitrogen contents of two membranes found to be 6.3% 8.0% respectively. Their electrical conductivity was measured ca. 200 S cm−1.
Controlled-sized crystals, from the nano to microscale, of biocompatible and highly stable porous iron(III) 3,3,′5,5′-azobenzenetetracarboxylate MIL-127(Fe) MOF have been successfully prepared with very high space-time-yields using different synthetic routes.
Despite increasing interest in metal-organic frameworks (MOFs) the biomedical field, developing specific formulations suitable for different administration routes is still a main challenge. Here, we propose simple, fast and bio-friendly press-molding method preparation of cutaneous patches based on composites made from drug nanocarrier MIL-100(Fe) biopolymers. The physicochemical properties (structure, hydration, bioadhesive swelling properties), as well their encapsulation release...
A novel, biocompatible, calcium-based coordination polymer was hydrothermally synthesized using as linker the bone antiresorptive bisphosphonate alendronate. Its structure determined single-crystal X-ray diffraction and characterized by chemical analysis, infrared spectroscopy (IR), powder (XRPD), solid state nuclear magnetic resonance (NMR) thermogravimetric analysis (TGA). bioactivity finally evaluated in vitro, revealing a very high stability towards simulated body fluid.
This work describes an easy two-step approach for metal nitride/carbide nanocomposite ceramic nanofibers via heat treatment of electrospun precursor fibers. Possibilities to tune their composition, carbon scaffold organization and texture depend on the calcination temperature, yield two different types fiber structures. Fiber mats with various morphologies were obtained from polyacrylonitrile–chromium chloride fibers, while well defined rod-like non-woven when a methylated polyurea was used...
The mesomorphic behavior, shape shifting, and shape-memory types of two homologous series main-chain liquid-crystalline co-elastomers (MC-LCEs) with composition-tunable transition temperatures mesophases structures are reported. weakly cross-linked macromolecules were prepared in a one-step procedure by the versatile platinum-catalyzed hydrosilylation reaction between siloxane oligomers (linear spacers netlike point molecules) binary mixtures, composed defined proportions divinylic monomeric...
A hybrid polymeric network has been achieved by using pre-functionalized 3.3 nm diameter iron oxide nanoparticles (NPs) as cross-linkers to reticulate mesogenic linear oligomers. room-temperature smectic mesophase is induced in the embedding NPs, and magnetic properties remain almost unchanged, despite substantial changes of environment around ferrite cores.
Fe3 N and C nanocomposites have a wide range of applications thanks to their ceramic nature, magnetic properties, conductivity catalytic activity, just cite some. In many fields optimal performances are ensured by crystallinity, homogeneity hierarchical organization. the present paper, crystalline, well-defined nanofibres iron nitride carbide/carbon nanocomposite with tunable composition size were prepared via electrospinning. The starting polymeric material was directly electrospun into...
